INHALER.

SPECIFICATION forming part of Letters Patent No. 254,391, dated February 28, 1882.

' Applicatioiffiled August], 1881. (Nomodeh) To all whom it may concern Be it known that I, WILLIAM F. SEMPLE, of Mount Vernon, in the county of Knox and State of Ohio, have invented certain new and useful Improvements in Inhalers; and I'do hereby declare the following to be a full, clear, and exact description of the invention, such as will en able others skilled in the art to which it pertains to make and use it, reference being bad to the accompanying drawings, which form part of this specification. V

My invention relates to inhalers; and it consists in certain features of construction and combination of parts, as will hereinafter be described, and pointed out in the claims.

In the drawings, Figure l is an isometric view of an inhaler made in accordance with my invention, wherein the container is made of glass, through which the mechanical part of the invention may be seen. Fig. 2 is a vertical sectional view of the same, and Fig. 3 is a plan view of the inside of the cover.

In the said drawings, A represents the container, which may be made of any suitable shape or material; but I prefer to make it, as shown in the drawings, of glass, in order that the operation ofthe mechanism contained in the interior may be clearly seen andthe amount of vapor may be regulated.

B represents a removable table, provided with legs B, which rest upon the bottom of the container. This table is adapted to support the air-pump O. D is a pipe leading from near the table at the bottom of the container to and through the cover E, through which air may pass from the outside to the interior of the "container.

F is the inhaling-pipe, through which the vapor may be drawn by the patient.

The air-pump 0 consists of a cylinder provided with a valve, G, at its bottom, through which air may pass as the piston N is raised,

and which closes as the piston is driven down ward. I is an air-pipe leading from the interior of the pump 0, and terminating ina small jet-orifice. K is a pipe leading from a point near the bottom of the container, and terminating opposite the jet-orifice of the air-pipe I.

L is a coiled spring placedrwithin the cylinder or air-pump O for the purpose of forcing the piston N upward. This pistonis operated by the rod N, which passes through the top of the container. The openings for the passage through the top of the pipes D and F and'pis ton-rod N should be packed with any suitable material. I have found cork to be a very suitable packing for this purpose, as shown in Fig. 3.

Having thus described the construction of my device, its operation is as follows:

The medicine whose fumes it is desired to inhale is placed in the bottom of the container in sufficient quantities to cover the lower end of the pipe K, as shown by dotted lines in Fig. 2. The piston-rod N may now be forced downward by the finger, which will force the air in the cylinder 0 out through the pipe I, which, terminating at the upper end of the pipe K, will draw the medicine through the pipe K and vaporize it in the chamber above the table B.

The piston-rod may now be released, when the spring 0 will force the piston M upward, the valve G will open, and the cylinder 0 will again fill with air. The piston-rod N may again be forced downward, and the same operations will follow, as described.

It will be apparent that by the use of my inhaler no medicine is lost, as all that is not drawn out through the inhaling-tube settles back into the bottom of the container.

What I claim is- 1. In an inhaler, the combination with a container for holding medicine and the vapor thereof, and an inhaling-tube attached to said container, of an atomizer located within said container, substantially as set forth.

2. In an inhaler, the combination of the container A, air-pump 0, having the pipe I, the pipe K, and the outlet or inhaling-tube F, substantially as and for the purposes shown.

In testimony whereofI have signed my name to this specification in the presenceof two subscribing witnesses.

WILLIAM F. SEMPLE.
